PLANTS, PEOPLE, PLANET, EarlyView.Asian elephants play crucial roles in ecosystem functioning, and their interactions with plants influence above‐ and belowground carbon cycling. We tested whether their mechanically destructive foraging triggers short‐term, stress‐induced shifts in tree root exudation, an underappreciated pathway linking herbivory to belowground carbon processes.

Occurrence of arthropod pests associated with Brassica carinata and impact of defoliation on yield
GCB Bioenergy, 2021 Brassica carinata has the potential to become an economical biofuel winter crop in the Southeast U.S. An IPM program is needed to provide management recommendations for B. carinata in the region. This study serves as the first steps in the developing IPM

Pest Management Science, EarlyView.Increasing canola plant density reduced flea beetle abundance per plant and increased yield, independent of region or insecticide use, highlighting its potential as a component of integrated pest management. Abstract The crucifer flea beetle, Phyllotreta cruciferae (Goeze), and the striped flea beetle, Phyllotreta striolata (Fabricius) (Coleoptera ...

Defoliation estimation of forest trees from ground-level images
bioRxiv, 2018 In this paper, we propose to estimate tree defoliation from ground-level RGB photos with convolutional neural networks (CNN). Tree defoliation is usually assessed with field campaigns, where experts estimate multiple tree health indicators per sample ...

Pest Management Science, EarlyView.Phakopsora pachyrhizi in Paraguay showed diverse resistance to DMI, SDHI, and QoI fungicides at both regional and intra‐field levels, likely driven by target mutation genes. Abstract BACKGROUND Phakopsora pachyrhizi, the causative agent of Asian soybean rust, poses a major threat to soybean production in South America. The rising incidence of fungicide

Effects of Invasive Winter Moth Defoliation on Tree Radial Growth in Eastern Massachusetts, USA
Insects, 2014 Winter moth, Operophtera brumata L. (Lepidoptera: Geometridae), has been defoliating hardwood trees in eastern Massachusetts since the 1990s. Native to Europe, winter moth has also been detected in Rhode Island, Connecticut, eastern Long Island (NY), New

Pest Management Science, EarlyView.SCB has a robust RNAi response to injected dsRNA, but oral RNAi is less efficient. Nucleases do not appear to be responsible for the discrepancy, suggesting other factors are involved. Abstract BACKGROUND The striped cucumber beetle (SCB) is a serious pest of cucurbit crops, causing damage both by feeding on plants and by vectoring plant diseases ...

Short-term effects of defoliation intensity on sugar remobilization and N fluxes in ryegrass
Journal of Experimental Botany, 2018 N uptake is positively correlated with photosynthetic capacity in ryegrass. The N sink strength of leaf meristems increased in response to defoliation. C and N reserves were remobilized only under severe defoliation.
